酸碱质子理论在有机化学中的应用

本文以酸碱质子理论为指导,研究了高级有机酸的分离提纯方法。一般分两步,第一步加碱溶液,使不溶于水的带机酸晶体溶解,通过过滤,除去泥沙等不溶性杂质。第二步加酸,有机酸晶体从溶液中析出,通过过滤除去可溶性杂质

The Thery of Proton of Acid and Ackali In the Use of Organic Chemistry

The paper is under the guidance of the theory of acid and alkali.The method of purification of high-quality organic acid has been studied. The method consists of two steps in general. The first step is to add seme alkaline solution of definite density in a definite quantity of the crude product of higb-guality organic acid . The solid of organic acid which does not dissowe in water dissolves in water dissolves. The mud and sand and some other foreign matters whic are undisslvable will be removed by a filter. The next step is to add some hydrochloric acid of definite density in the solution which has been purified by the ficter. The crystal of organic acid will separate out. The dissowable foreign matters will be remoAed by a filter and the better pure crystal of high-quality organic acid.
